Abstract

A door damper ( 100 ) is made preferably of heat-resistant plastic material and comprises a damper element ( 150 ) as well as a pestle ( 110 ) that is securely guided in the housing ( 120 ) of the door damper. As an integrated structure, it can be mounted at any suitable location at a household appliance ( 160 ) that is cool and the pestle ( 110 ) can directly contact the front door ( 220, 300 ). Beneficially, it comprises an orifice ( 140 ) at the housing ( 120 ) to fix it at a sidewall of a household appliance ( 161 ) or at the front door ( 220, 300 ). Beneficially, the door damper also comprises a switch ( 145 ) that allows switching a door alarm, a light or influencing cooking functions.

First claim

The invention claimed is:

1. A household appliance comprising a
a door supported at a hinge, and
a door damper mounted in a region of the household appliance in proximity to the hinge and having at least one cavity arranged opposite to the door and defining an opening plane section on that side,
wherein the door damper comprises a damper element and a pestle in force-transmitting contact with the damper element,
wherein the door comprises a support frame for supporting at least one glass panel, said door having at least one section where a section of said support frame supports at least two sections of said one glass panel, and
wherein the pestle is arranged to contact a side of said section of the support frame that is opposite a side of the section of the support frame that supports the glass panel,
wherein the pestle provides a front surface in contact with the door when the door is positioned in or within an angle relative to the opening plane, the angle being an angle between the door and the opening plane,
wherein, after the door contacts the pestle, further movement of the door toward the door damper actuates the pestle.

2. The household appliance according to claim 1 , wherein the front surface of the pestle is formed to have a shape selected from the group consisting of the angle between the door and the opening plane, convex, oval, semicircular, tapered, rectangular, and flat.

3. The household appliance according to claim 1 , wherein the pestle is fixed to the damper element and/or wherein the length of the pestle is at least partially adjustable.

4. The household appliance according to claim 1 , wherein the pestle is actuated at an angle between 0° and 30°.

5. The household appliance according to claim 1 , wherein the housing and/or the pestle is made from heat-resistant plastic material.

6. The household appliance according to claim 1 , wherein the pestle has a shape adapted to operate a switch and/or has a notch, which may get in contact with an actuator in order to operate the switch.

7. The household appliance according to claim 1 , wherein the damper element operates pneumatically or hydraulically and has a linear or a progressive damping characteristic.

8. The household appliance according to claim 1 , wherein the door damper is mounted on a support structure that supports the hinge.

9. The household appliance according to claim 1 , wherein the door damper is arranged on and/or in a region of a double fulcrum hinge.

10. The household appliance according to claim 1 , wherein the door damper and/or the pestle is actuated by the door when a first force, which is provided by the hinge and applied to the pestle via the door, is reached, which exceeds a second force, which is a counterforce provided by the door damper and/or the pestle.

11. The household appliance according to claim 1 , wherein the door damper can be fixed directly on a hinge and/or at associated mechanical parts.

12. The household appliance according to claim 1 , wherein the door damper comprises a housing having a bracket, wherein the pestle is guided by the housing.

13. The household appliance according to claim 1 , wherein the pestle is in connection with a switch.

14. The household appliance according to claim 4 , said angle being between 5° and 25°.

15. The household appliance according to claim 4 , said angle being between 0° and 10°.

16. The household appliance according to claim 5 , said plastic material being heat-resistant up to 350° C. and/or being heat-insulating.

17. The household appliance according to claim 9 , said double fulcrum hinge being spring-loaded.

18. The household appliance according to claim 10 , wherein the first force and the second force are adapted to each other such that the door closes automatically with a predetermined closing speed, at least when positioned in an angle between 0° and 30°.

19. The household appliance according to claim 1 , wherein the pestle is removably disposed in a housing of the door damper.
